| However that measurement depends on the size of your display and |
| there is no standard display density. At present there is not a |

| When CONFIG_CFB_CONSOLE is defined, the video console is the |
| default console. The serial console can be forced by setting the |
| environment 'console=serial'. |
| |
| config CFB_CONSOLE_ANSI |
| bool "Support ANSI escape sequences" |
| depends on CFB_CONSOLE |
| help |
| This allows the colour buffer frame buffer driver to support |
| a limited number of ANSI escape sequences (cursor control, |
| erase functions and limited graphics rendition control). Normal |
| output from U-Boot will pass through this filter. |
| |
| config VGA_AS_SINGLE_DEVICE |
| bool "Set the video as an output-only device" |
| depends on CFB_CONSOLE |
| default y |
| help |
| If enable the framebuffer device will be initialized as an |
| output-only device. The Keyboard driver will not be set up. This |
| may be used if you have no keyboard device, or more than one |
| (USB Keyboard, AT Keyboard). |
| |
| config VIDEO_SW_CURSOR |
| bool "Enable a software cursor" |
| depends on CFB_CONSOLE |
| default y if CFB_CONSOLE |
| help |
| This draws a cursor after the last character. No blinking is |
| provided. This makes it possible to see the current cursor |
| position when entering text on the console. It is recommended to |
| enable this. |
| |
| config CONSOLE_EXTRA_INFO |
| bool "Display additional board information" |
| depends on CFB_CONSOLE |
| help |
| Display additional board information strings that normally go to |
| the serial port. When this option is enabled, a board-specific |
| function video_get_info_str() is called to get the string for |
| each line of the display. The function should return the string, |
| which can be empty if there is nothing to display for that line. |
| |
| config CONSOLE_SCROLL_LINES |
| int "Number of lines to scroll the console by" |
| depends on CFB_CONSOLE || DM_VIDEO || LCD |
| default 1 |
| help |
| When the console need to be scrolled, this is the number of |
| lines to scroll by. It defaults to 1. Increasing this makes the |
| console jump but can help speed up operation when scrolling |
| is slow. |
| |
| config SYS_CONSOLE_BG_COL |
| hex "Background colour" |
| depends on CFB_CONSOLE |
| default 0x00 |
| help |
| Defines the background colour for the console. The value is from |
| 0x00 to 0xff and the meaning depends on the graphics card. |
| Typically, 0x00 means black and 0xff means white. Do not set |
| the background and foreground to the same colour or you will see |
| nothing. |
| |
| config SYS_CONSOLE_FG_COL |
| hex "Foreground colour" |
| depends on CFB_CONSOLE |
| default 0xa0 |
| help |
| Defines the foreground colour for the console. The value is from |
| 0x00 to 0xff and the meaning depends on the graphics card. |
| Typically, 0x00 means black and 0xff means white. Do not set |
| the background and foreground to the same colour or you will see |
| nothing. |
| |
| config LCD |
| bool "Enable legacy LCD support" |
| help |
| Define this to enable LCD support (for output to LCD display). |
| You will also need to select an LCD driver using an additional |
| CONFIG option. See the README for details. Drives which have been |
| converted to driver model will instead used CONFIG_DM_VIDEO. |
| |
| config VIDEO_DW_HDMI |
| bool |
| help |
| Enables the common driver code for the Designware HDMI TX |
| block found in SoCs from various vendors. |
| As this does not provide any functionality by itself (but |
| rather requires a SoC-specific glue driver to call it), it |
| can not be enabled from the configuration menu. |
| |
| config VIDEO_SIMPLE |
| bool "Simple display driver for preconfigured display" |
| help |
| Enables a simple generic display driver which utilizes the |
| simple-framebuffer devicetree bindings. |
| |
| This driver assumes that the display hardware has been initialized |
| before u-boot starts, and u-boot will simply render to the pre- |
| allocated frame buffer surface. |
| |
| config VIDEO_DT_SIMPLEFB |
| bool "Enable SimpleFB support for passing framebuffer to OS" |
| help |
| Enables the code to pass the framebuffer to the kernel as a |
| simple framebuffer in the device tree. |
| The video output is initialized by U-Boot, and kept by the |
| kernel. |
| |
| config OSD |
| bool "Enable OSD support" |
| depends on DM |
| default n |
| help |
| This supports drivers that provide a OSD (on-screen display), which |
| is a (usually text-oriented) graphics buffer to show information on |
| a display. |
| |
| config SANDBOX_OSD |
| bool "Enable sandbox OSD" |
| depends on OSD |
| help |
| Enable support for sandbox OSD device used for testing purposes. |
| |
| config IHS_VIDEO_OUT |
| bool "Enable IHS video out driver" |
| depends on OSD |
| help |
| Enable support for the gdsys Integrated Hardware Systems (IHS) video |
| out On-screen Display (OSD) used on gdsys FPGAs to control dynamic |
| textual overlays of the display outputs. |
